How to Upgrade or Patch a ZFS Root File System With Zone Roots (at Least Solaris 10 5/09)

Use this procedure when you need to upgrade or patch a ZFS root file system with zone roots in at least the Solaris 10 5/09 release. These updates can either be a system upgrade or the application of patches.

In the steps that follow, zfs2BE, is the example name of the boot environment that is upgraded or patched.

1. Review the existing ZFS file systems.

   # zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 7.38G 59.6G 100K /rpool rpool/ROOT 4.72G 59.6G 21K legacy rpool/ROOT/zfs2BE 4.72G 59.6G 4.64G / rpool/ROOT/zfs2BE@zfs2BE 75.0M - 4.64G - rpool/ROOT/zfsBE 5.46M 59.6G 4.64G / rpool/dump 1.00G 59.6G 1.00G - rpool/export 44K 59.6G 23K /export rpool/export/home 21K 59.6G 21K /export/home rpool/swap 1G 60.6G 16K - rpool/zones 22.9M 59.6G 637M /rpool/zones rpool/zones-zfsBE 653M 59.6G 633M /rpool/zones-zfsBE rpool/zones-zfsBE@zfs2BE 20.0M - 633M -

2. Ensure that the zones are installed and booted.

   # zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / native shared 5 zfszone running /rpool/zones native shared

3. Create the ZFS BE to upgrade or patch.

   # lucreate -n zfs2BE Analyzing system configuration. Comparing source boot environment <zfsBE> file systems with the file system(s) you specified for the new boot environment. Determining which file systems should be in the new boot environment. Updating boot environment description database on all BEs. Updating system configuration files. Creating configuration for boot environment <zfs2BE>. Source boot environment is <zfsBE>. Creating boot environment <zfs2BE>. Cloning file systems from boot environment <zfsBE> to create boot environment <zfs2BE>. Creating snapshot for <rpool/ROOT/zfsBE> on <rpool/ROOT/zfsBE@zfs2BE>. Creating clone for <rpool/ROOT/zfsBE@zfs2BE> on <rpool/ROOT/zfs2BE>. Setting canmount=noauto for </> in zone <global> on <rpool/ROOT/zfs2BE>. Creating snapshot for <rpool/zones> on <rpool/zones@zfs10092BE>. Creating clone for <rpool/zones@zfs2BE> on <rpool/zones-zfs2BE>. Population of boot environment <zfs2BE> successful. Creation of boot environment <zfs2BE> successful.

4. Select one of the following to upgrade the system or apply patches to the new boot environment:

   • Upgrade the system.

     # luupgrade -u -n zfs2BE -s /net/install/export/s10up/latest

     where the -s option specifies the ___location of the Solaris installation medium.

     This process can take a very long time.

     For a complete example of the luupgrade process, see Example 5–6.

   • Apply patches to the new boot environment.

     # luupgrade -t -n zfs2BE -t -s /patchdir patch-id-02 patch-id-04

5. Activate the new boot environment.

   # lustatus Boot Environment Is Active Active Can Copy Name Complete Now On Reboot Delete Status -------------------------- -------- ------ --------- ------ ---------- zfsBE yes yes yes no - zfs2BE yes no no yes - # luactivate zfs2BE A Live Upgrade Sync operation will be performed on startup of boot environment <zfs2BE>. . . .

6. Boot from the newly activated boot environment.

   # init 6

Example 5–6 Upgrading a ZFS Root File System With a Zone Root to a Oracle Solaris 10 9/10 ZFS Root File System

In this example, a ZFS BE (zfsBE), which was created on a Solaris 10 10/09 system with a ZFS root file system and zone root in a non root pool, is upgraded to the Oracle Solaris 10 9/10 release. This process can take a long time. Then, the upgraded BE (zfs2BE) is activated. Ensure that the zones are installed and booted before attempting the upgrade.

In this example, the zonepool pool, the /zonepool/zones dataset, and the zfszone zone are created as follows:

# zpool create zonepool mirror c2t1d0 c2t5d0
# zfs create zonepool/zones
# chmod 700 zonepool/zones
# zonecfg -z zfszone
zfszone: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:zfszone> create
zonecfg:zfszone> set zonepath=/zonepool/zones
zonecfg:zfszone> verify
zonecfg:zfszone> exit
# zoneadm -z zfszone install
cannot create ZFS dataset zonepool/zones: dataset already exists
